Description: PI-Change is a prior-informed multiple change point detection
    method that incorporates prespecified plausible change point locations
    through a time-varying penalized likelihood. The method extends multiple
    change point detection beyond purely data-driven segmentation by allowing
    external knowledge about plausible change point locations to enter the
    objective function; see Jacobs and Chen (2026)
